Definitions

  • the invention is directed to a surgical instrument having a cylindrical tube for accommodating a guidewire therein.
  • Surgical instruments such as scalpels, are used to make an incision in the skin, enabling insertion of devices whose purpose is to deliver various substances to the body.
  • a guidewire is inserted into the body cavity and instruments can be reliably advanced over the guidewire and into the body cavity for proper placement. This method is known as the “Seldinger Technique.”
  • the guidewire incision needs to be widened in order to accommodate larger medical devices such as a trocar or catheter. The enlargement is typically done by hand which may lead to an imprecise or larger than needed cut. Therefore, a need clearly exists for a surgical instrument capable of using the guidewire to aid a surgical device, such as a scalpel, in making a more precise incision
  • the present invention provides a surgical instrument with a cylindrical tube affixed thereto.
  • the cylindrical tube is affixed to a top edge of the surgical instrument.
  • the cylindrical tube may be affixed to any side (e.g., side or bottom) depending upon the intended use of the surgical instrument.
  • the cylindrical tube is affixed close to the tip of the surgical instrument to minimize the distance between the tip of the surgical instrument and the edge and the guidewire. This allows a user, for example, to minimize the size of an incision and to eliminate the potential for inadvertent skin nicks.
  • the surgical instrument can also be housed in a sheath.
  • FIG. 1 is a view of the surgical instrument having a cylindrical tube attached thereto.
  • FIG. 2 is a view of the surgical instrument of FIG. 1 with a guidewire inserted through the cylindrical tube.
  • FIGS. 3-5 are views of an alternate embodiment of the surgical instrument encased in a sheath.
  • Distal end 104 has cylindrical tube 106 affixed to the edge of the surgical instrument 100 for accommodating a guidewire. As shown, cylindrical tube 106 is affixed to the top edge of the surgical instrument 100 . However, cylindrical tube 106 may be affixed to any side (e.g., sides or bottom) depending upon the intended use of surgical instrument 100 .
  • Proximal end 102 preferably comprises a handle to allow a user to operate surgical device 100 .
  • surgical instrument 100 is a scalpel having cutting edge 108 for cutting a skin surface.
  • Cutting edge 108 may comprise a cap or cover in order to protect a user and prevent cutting edge 108 from dulling.
  • Cylindrical tube 106 is affixed close to tip 110 of surgical instrument 100 to minimize the distance between tip 110 and the edge and a guidewire inserted through cylindrical tube 106 .
  • guidewire 112 is threaded through cylindrical tube 106 as depicted in FIG. 2 .
  • Surgical instrument 100 can then be advanced over guidewire 112 to a skin surface (not shown).
  • An incision can then be made using cutting edge 108 .
  • the incision is precise because cylindrical tube 106 limits the range of movement of surgical instrument 100 , thereby avoiding any inadvertent skin nicks to the skin surface. Additionally, the cylindrical tube 106 allows for precise movement of surgical instrument 100 , thereby eliminating residual skin tags after incision that may prevent smooth advancement of catheters or devices over the guidewire 112 .
  • FIGS. 3-5 An alternate embodiment of surgical instrument 100 is depicted in FIGS. 3-5 .
  • surgical instrument 100 can be encased in sheath 200 .
  • Sheath 200 has a first channel 202 for accommodating the connection between button 204 and surgical instrument 100 .
  • Button 204 is used to move surgical instrument 100 from a closed position ( FIG. 4 ) to an open position ( FIG. 3 ).
  • the surgical instrument is maintained in the open and/or closed position by a locking mechanism, similar to that of a utility knife.
  • Sheath 200 further comprises a second channel 206 for accommodating cylindrical tube 106 when surgical instrument 100 is in a closed position.
  • Sheath 200 protects an operator from lacerations while threading guidewire 106 through cylindrical tube 106 .
  • surgical instrument 100 remains in a closed position ( FIG. 4 ).
  • Surgical instrument 100 can then be advanced to an open position ( FIG. 3 ) when surgical instrument 100 is close to the desired incision location.
